On Wednesday, gunmen wielding AK-47 rifles opened fire and hurled grenades at a patrol car in Pacific resort town of Zihuatanejo, killing four officers.
The car caught fire, and the bodies of the officers were found burned inside, the Guerrero state Public Safety office said in a statement.
An hour later, gunmen shot at a police station near the Zihuatanejo airport, but nobody was hurt. It was unclear if the same assailants were behind both attacks.
For those of you who've been to Zihua, I believe "the police station near the airport" is the one when you just leave town on your way to the airport.
